“…Counting again with the support of the foundry company, a surface feature resulting from the honing of cast irons-folded metal -was well described and deserves to be highlighted [308]. Results of lubricated wear [309] and the combination of plasma and laser technologies to improve the performance of vermicular cast irons [310,311] have been published.…”

This first regional issue published in STMP highlights the potential and importance of the research carried out in Latin America regarding surface engineering and tribology. In order to celebrate this important initiative, a complete historical account of Brazilian tribology is presented for the first time. It initiates with the first steps of Brazilian tribology in the 1980s, followed by the evolution and expansion of tribology research both in academic centres and industry. Focus is given to two outstanding achievements of Brazilian tribology: the fully flexible engines that run at any proportion of ethanol and gasoline and a fully innovative, completely oil-less family of hermetic compressors. The status-quo of the current research groups on tribology is described. Finally, the future trends envisaged by the Brazilian tribology community are presented.

Difficult-to-cut alloys, which include titanium, cobalt, nickel alloys, and high-strength and heat-resistant steels, can nowadays be manufactured using selective melting (SLM), and products made of such materials are widely used in aerospace, automotive, and medical applications. SLM is widely used among other methods of additive manufacturing (AM) for the production of parts with complex geometry which are difficult to produce using conventional manufacturing processes. In this review article, for the first time, a comprehensive literature review of the most important parameters which influence the SLM manufacturing process of difficult-to-cut alloys is discussed and analysed. Parameters such as composition, grain size, defects, texture, and thermo-mechanical properties and their effect on surface integrity, namely surface topography (machined surface defects, surface roughness, surface texture), microstructural alterations (plastic deformation, grain refinement, and orientation, white layer formation), and mechanical properties (work hardening layer formation and microhardness, residual stress) are discussed. As a result, this review article shows the advantages and disadvantages of using various compositions, classifications, microstructure, defects, and properties of SLM of difficult-to-cut alloys on surface integrity and outlines development prospects, challenges, and future trends.
